    • In the case of an agitator shaft (1) of a fermenter of a biogas plant, comprising agitator brackets (12), which are arranged on a shaft wall (10) and on which at least one agitating arm (2), comprising an agitating arm fastening portion (20) and a blade carrier (21) can be connected to the agitator brackets (12) by means of fastening two agitating arm fastening plates (200) of the agitating arm (2), it is intended to provide a method that achieves easier and quicker assembly of an agitator shaft and integration in a fermenter in situ, whereby a considerable cost saving in the setting up of a fermenter is achieved. This is achieved by cutting out fastening holes in the agitator brackets (12) and cutting out through-holes in the agitating arm fastening plates (200) in such a way that a plurality of retaining ring bolts (3) can be arranged so as to pass completely through the fastening holes and the through-holes and can be riveted therein.
    • 在发酵罐的搅拌器轴的情况下,其包括搅拌器支架,其布置在轴壁上,并且包括搅拌臂紧固部分和叶片载体的至少一个搅拌臂可以连接到其上 搅拌器支架通过紧固搅拌臂的两个搅拌臂紧固板,旨在提供一种方法,其实现了更容易和更快速地组装搅拌器轴并将其集中在发酵罐中,从而可以节省相当多的成本 发酵罐实现。 这是通过在搅拌器支架中切出紧固孔并切割搅拌臂紧固板中的通孔来实现的,使得多个保持环螺栓可以被布置成完全穿过紧固孔和通孔 可以铆在其中。
